WEATHER-STRIP.

SPECIFICATION forming part of Letters Patent No. 724,067, dated March 31, 1903.

Application filed August 2,1902.

To all whom it may concern:

Be it known that 1, ROBERT H. WHITTED, a citizen of the United States, residingat Crawfordsville, in the county of Montgomery and State of Indiana, have invented a new and useful Weather-Strip, of which the following is a specification.

The invention relates to improvements in weather-strips.

The object of the present invention isto improve the construction of weather-strips and to provide a simple, inexpensive, and of ficient one of great strength and durability adapted to be readily applied to a door and capable of automatic operation to close the crack or space at the bottom of a door when the latter is shut and to assume an elevated position to clear the floor and its covering when the door is opened.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of a portion of a door provided with a weather-strip constructed in accordance with this invention, the door being open. Fig. 2 is a detail view of the Weatherstrip proper and the reciprocating rod for raising and lowering the same. Fig. 3 is a vertical sectional View of the same. Fig. 4 is a detail perspective view of a portion of the inner stationary plate which forms the back of the casing. Figs. 5 and 6 are detail sectional views taken longitudinally of the ends of the device. 7

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a vertically-movable weatherstrip constructed of sheet metal or other suit- Serial No- 118,138. (No model.)

ward to form the inner side of the groove 3. The sheet metal is compressed against the rubber strip 2, which is tightly held in the groove. The upper portion of the metal of the vertically-movable weather-strip is bent inward to form an approximately L-shaped top flange or portion 4, which fits against the inner face of the casing in which the vertically-movable weather-stri p is mounted. a

The casing in which the vertically-movable weather-strip is mounted consists of an inner or back plate 5 and an outer or front plate 6. The inner or back plate 5,which is secured by screws or other suitable fastening devices to the door 7, has its lower portion bent outward and upward to form a bottom groove 8 for the reception of a reciprocating rod 9, which is adapted to actuate the vertically-movable strip, as hereinafter explained. The front plate of the casin g covers the upper portion of the vertically-movable strip and is provided at its top with an L-shaped flange 10, which is secured by screws 11 to the door, as clearly shown in Fig. 1. The outer or frontplate forms a guard or shield for excluding moisture from the interior of the weather-strip. The bottom of the inner or back plate is approximately U-shaped, and the reciprocating rod 9, which is designed to project beyond the hinged edge of the door when the latter is open, is provided between its ends with curved bends 12, forming cams and adapted to engage inclined ways of the vertically-movable weatherstrip. These inclined ways, which may be of any desired construction, preferably consist of lower lugs 13 and upper pulleys 14; but they may consist of a pair of lugs or a pair of pulleys. The projecting end 15 of the rod extends through an opening 16 of the inner or rear plate, which is provided with an L-shaped end flange 17, forming one end of the casing. The other end of the inner or back plate is provided with a similar flange 18, and it has a longitudinal socket 19, consisting of a tube and receiving one end of a coiled spring 20, which is disposed on the reciprocating rod and which is adapted to actuate the same in one direction when the rod is free to move. The rod is arranged ata slight inclination, as illustrated in Fig. 2 of the drawings, to cause the end of the weatherstrip at the free edge of the door to respond quickly to the action of the spring when the door is opened, whereby the weather-strip is prevented from dragging on the floor. The socket for the spring and the opening for the projecting end of the rod retain the latter in proper position, and the bends 12, which form the cams, are approximately semicircular. By this construction the weatherstrip is readily raised and lowered when the rod is reciprocated.

It will be seen that the Weather-strip is simple and comparatively inexpensive in construction, that it is positive and reliable in operation, and thatit is adapted to be readily applied to a door.

The cam-shaped bends of the rods by being similarly curved at opposite sides enable the rod to be readily reversed for operating on either a right or left hand door, and the weather-strip is adapted to be applied to a door hung at either edge.

What I claim is 1. A device of the class described comprising an inner or back plate provided at its bottom with an outwardly-projecting portion forming a groove, an outer or front plate forming a guard or shield and provided at the top with a flange, a vertically-movable weather-strip located within the casing and having inclined ways, and a reciprocating spring-actuated rod mounted within the easing and provided with cam-bends engaging the ways, substantially as described.

2. A device of the class described comprising an inner or back plate provided at its hot tom with a curved flange forming a longitudinal groove, said plate being also provided at its ends with upright flanges forming end walls, an outer or front plate provided at the top with an approximately L-shaped flange, a vertically-movable Weather-strip arranged within the casing and provided at its top with a longitudinal flange and having its lower portion arranged on the exterior of the inner or back plate, and means for raising and lowering the Weather-strip, substantially as described.

3. A device of the class described comprising a casing composed of an inner or back plate having an approximately U shaped bottom portion and provided with upright end walls, one of the end Walls being also provided with an opening, a socket arranged within the bottom portion of the inner or back plate, at the other end thereof, and a front plate provided at the top with a flange and having its lower portion spaced from the bot tom of the inner or rear plate, a verticallymovable Weather-strip, a spring engaging the socket of the casing, and a rod extending through the opening of the casing and engaged by the said spring and provided with cams for actuating the weather-strip, substantially as described.

In testimony that I claim the foregoing as my oWn I have hereto affixed my signature in the presence of two witnesses.
